It looks as though the answer is going to be Olympus. A significant factor in that decision is that, as several people (including my wife) pointed out to me, it doesn't matter how good your camera is if it's sitting at home because it's too heavy to carry around (and unfortunately you don't want to leave anything valuable in your car at many of the tourist spots round here). The decision was also influenced by the fact that Olympus kindly chose to put their top-of-the-line sports & wildlife body - the OM-D E-M1X - on sale for the next couple of weeks, so that instead of being $3000 I could get it for less than the cost of a K-3iii. Of course that's without any lenses ... Fortunately I've alread got a couple of Olympus Micro 4/3 lenses lying around - a 12-40mm and 40-150mm - that I bought some years ago for my wife (together with an Olympus Pen EPL-1); I've got a better 40-150 coming along with the body, but I'll be able to use the 12-40 until I decide what to buy to cover those focal lengths. So I guess that, assuming everything goes as planned, at some point I'll be putting at least some of my Pentax gear up for sale. (And yes, that *will* include the FA* 250-600/f5.6). It will seem strange not to be using a Pentax as my everyday camera; it's almost 50 years since I bought myself a Spotmatic II along with a 50mm f1.4 lens, and I've stuck with Pentax ever since. (MX, ME, ME Super, Super Program, PZ-1p, MZ-S, *ist-D, K10D, K5). That doesn't mean you'll be able to kick me off the PDML, though! -- %(real_name)s Pentax-Discuss Mail List To unsubscribe send an email to pdml-le...@pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
